Olivier Giroud says Alexis Sanchez will bring a new dimension to Arsenal's attack

Gunners boss Arsene Wenger splashed out £35m to bring the Chile World Cup star to the Emirates following the summer's finals in Brazil.

Sanchez played only 45 minutes of last Sunday's 3-0 Community Shield victory over Premier League champions Manchester City.

Although his Wembley performance was fleeting, Giroud has been left in no doubt that Arsenal have got themselves a huge talent on their hands.

"I saw him play with Chile in the World Cup and thought he did really well, but I didn't know then he was coming to Arsenal," Giroud told SPORT magazine.

"When I heard they were signing him I thought: 'Yeah, if he can sign it would be great because he's a top player'.

"And he comes from Barcelona - a fantastic team where he played well. He will bring his experience and maybe something new we didn't have before."

Defenders Mathieu Debuchy and Calum Chambers as well as goalkeeper David Ospina have also arrived at the club this summer along with Sanchez.

“We have built a great team, but it will be a tough season because Chelsea have made some great signings as well”

And Giroud is confident the new arrivals will ensure that the Gunners will be able to sustain a title challenge this campaign, having seen their chances of capturing their first league crown since 2004 disintegrate in the final three months of last season.

"I think it's different now, because we are stronger than we have been in years before," he added.

"Last year we were top of the league maybe 18 times until March, so with our quality and quantity now we will give our best to reach our target.

"We have built a great team, but it will be a tough season because Chelsea have made some great signings as well.

"We will have Liverpool and both Manchester clubs pushing us, too. It's always tough to win the league, as we saw when Chelsea and Liverpool lost the title from nothing last year.
